I was pulling and pushing fairly hard. Probably over 80lbs of force. Matt from PM said he has seen this in very large mills as well. I am now of the mind that flex of the column in the y direction probably is not that critical. I don't think side milling should apply a lot of force in that direction. Drilling or plunging may but often don't need to be as accurate. I have never measured the flex of my column in the x direction, but I think that would make a bigger difference in milling accuracy. BTW There are several good writeups on reinforcing your specific mill. I think this mill might be an x2...
Thats not the same machine at all. I think its a grade above mine but thank you. My machine has an hollow rectangular boxed column with a 2" riser block to give me 13" between the spindle and table. The column mounts to the base in the same fashion as your PM-727. It flexes about .002-.003" with light pressure from 2 fingers. If I yank on it real hard it will probably cut .010" ! but I can still side mill and plunge mill on mild steel but at low doc.
I cheated on the handle as I don't have a lathe. I stole the handle off a cheap plastic faced hammer from a small punch set. The black is just the way it came in the box. I dinged the finish up on the narrow part so just cleaned it up with sandpaper. I have done hot bluing before with sodium nitrate and lye. The finish can turn out extremely nice, but its a bit of a pain. Here is the website I followed to do it.Sloth,
Love the hammer that you made. I really like the contrast with the copper - can you tell me what did on the lower part to get the black finish. Is it blueing or just a good coat of that black sharpie in the picture?
Thanks!
I used 2 of the 50 gram kits. I will post the price list I had from earlier this year. They also give calculations on it to figure out about how much you will need for your application. There is also some release agent listed on the form. The 50 gram cans are not on the list, but you can ask for them when you call. The ordering was pretty easy over the phone. You can also get a 100 gram can for about $20. The syringes are nothing special, but since there is a limited pot life you want to be able to fit what you need in a syringe or two to save time. You can buy some even bigger syringes for administering oral meds to horses and such at ranch supply stores.Wow I thought the Diamant would be way more expensive! I too watched Stefan's video and wanted to try this product. Your the first person I have heard mention using it and posting in the forums. I went to the link for Diamant that Stefan posted and of course I got lost. When I go to order do I just tell them I need 50 gram kit of DWH 310 FL: $13.00 ? Is the release agent Icheard others discussing available from them as well?
The syringe looks to be a standard syringe? I am pretty sure I have one or 2 laying around.
You stated you used all 50 grams of the DWH. My mill column and base mount the same way but its just a little smaller. Do you think the 50 g's is enough?
Sorry for all the questions. I will be doing this to my X2 and then when I get my PM-25 .
Here are a couple sites for the x2 column stiffening. Not sure if this is the same type of column as yours.
